Image compression reduces network requirements in a major way.
- Smaller files means less bandwidth
- Less round trips for faster page rendering
- reduces load on network function like proxies, IDS, etc.
And its already in production for Android devices using Google services.
To help everyone be able to see the beautiful photos that photographers share to Google+ in their full glory, we’ve turned to machine learning and a new technology called RAISR. RAISR, which was introduced in November, uses machine learning to produce great quality versions of low-resolution images, allowing you to see beautiful photos as the photographers intended them to be seen. By using RAISR to display some of the large images on Google+, we’ve been able to use up to 75 percent less bandwidth per image we’ve applied it to.
